I am enjoying listening to Derek Bell on the February Motor Sport magazine podcast so much that I have to plug it:
A couple of filmed laps are mentioned, both of which are superb viewing. I have tracked both down on YouTube, choosing to link to them rather than embed, as the latter often makes blog-pages clunky to load.
The first here is a lap of the old Nürburgring in a Porsche 956. The second here is again in the 956, and features a lap at Le Mans (followed by another) including the old four-mile Mulsanne straight uninterrupted by chicanes.
All links open in new windows.
